AAA stands for what in the material?

• A. Authentication, Authorization, and Accounting
• B. Access, Audit, and Assurance
• C. Authorization, Access, and Analysis
• D. Accounting, Access, and Authentication

Answer: (A)

AAA stands for Authentication, Authorization, and Accounting. This trio covers how we control access and track what happens: Authentication verifies the user's identity; Authorization enforces what actions the user is permitted to perform; Accounting records the user's activities and resource usage for auditing and accountability. In PCI DSS contexts, implementing these three steps ensures that only verified individuals can access cardholder data, that their permissions are appropriate, and that every action is logged for traceability. The other options use terms that aren’t the standard trio, so they don’t represent the recognized security model.
